Detailed Description

As shown in fig. 1, the cable bridge for quick maintenance comprises a bridge main body part 1, wherein a layout cavity 13 is arranged in the bridge main body part 1, more than one cable 65 is arranged in the layout cavity 13 in the bridge main body part 1, the cable 65 passes through a cable hole in the bridge main body part 1 and extends out of the bridge main body part, a section of the cable 65 in the layout cavity 13 forms a hollow section 6, and one end of the cable 65 extending out of the bridge main body part 1 is provided with a spring telescopic section 2 for stretching the external cable 65 into the layout cavity 13;

the top surface of the laying cavity 13 is provided with more than one guide rail 5 along the length direction of the cable, each guide rail 5 is over against one cable, two sliding blocks 7 are arranged on each guide rail 5 in a sliding mode, the two sliding blocks 7 are respectively arranged on two sides of the bridge main body part 1 and are close to cable holes, the two sliding blocks 7 are connected through more than one elastic piece 9, and when the two sliding blocks 7 are located at two ends of the guide rails 5, the elastic pieces 9 are in a stretching mode.

As shown in fig. 2, each of the sliders 7 is provided with a sliding assembly cavity 71, the sliders 7 are slidably mounted on the guide rail 5 through the sliding assembly cavities 71, the sliders 7 are provided with through holes in a penetrating manner, cables penetrate through the through holes and are bonded and fixed by glue, and when the sliders 7 slide, the cables can be driven to move along the guide rails, so that the cables are ejected out of the main body of the bridge.

In this embodiment, the elastic members 9 are elastic belts, the sliding blocks 7 are provided with the connecting lugs 8, the elastic belts are mounted on the connecting lugs 8, when the two sliding blocks 7 move from the extreme positions at the two ends of the guide rail 5, the elastic belts are in a stretching shape and used for resetting the two sliding blocks 7, and when the sliding blocks realize the limiting force, the two sliding blocks can be drawn together by the elastic belts to reset, so that the hollow section of the cable is bent and ejected out of the main body part of the bridge.

Wherein, be located and seted up an inspection opening 11 on the bottom surface of laying chamber 13, the hollow section 6 of cable is facing to the fixed balancing weight 12 of the equal suit of inspection opening, when two sliders 7 are close mutually, the hollow section 6 of cable is crooked and pass inspection opening 11 and stretch out in the outside of crane span structure main part 1, be used for two sliders 7 when being close mutually during balancing weight 12's effect, bend along balancing weight 12 department, the hollow section of cable after bending passes the inspection opening and stretches out in the outside of crane span structure main part, as shown in figure 4, the staff can overhaul the cable that has the problem the very first time this moment.

In this embodiment, as shown in fig. 3, a closed air storage cavity 62 is formed inside the hollow section 6 of the cable, two floating needles 61 are respectively disposed on two sides of the hollow section 6 of the cable, a needle hole 72 is disposed between the through hole of the slider 7 and the sliding assembly cavity 71 through inflation of the air storage cavity 62 and expansion of the cable, and the floating needles 61 penetrate through the needle hole 72 and are inserted into positioning holes (not shown) at the bottom of the guide rail to prevent the slider 7 from sliding on the guide rail 5. The inflation well hollow section can be with floating the needle and pressing and insert in the locating hole of guide rail bottom, in case the cable top layer is ageing damaged, perhaps because other reasons lead to when the cable top layer is damaged like the conflagration, inside gas emits the back, and the cable resumes deformation, and the needle that floats this moment separates with the locating hole, and the slip this moment loses spacingly, resets under the effect of elastic component for the cable is laid and is laid one section bending in the chamber and ejecting. The cable after being ejected can be isolated from other cables, so that the maintenance is convenient, and the safety of laying other cables is facilitated.

In this embodiment, the outside fixed mounting of crane span structure main part 1 has support 3, all has jib 4 through screw fixed mounting on support 3, and jib 4 passes through screw fixed mounting on the building body.
